Core features of mystical-type experiences induced by psilocybin include unity, sacredness, humility, authenticity, positive moods, transcendence of time and space, and ineffability.

“But the feature of that sense of unity, the interconnectedness of all things, and the truth value of that experience, I think, are the features that underscore this reorganizational component for many people.”

“And as unlikely as it sounds, we actually have good psychometric measures of those experiences, and they've been really well described, and in the core features of those experiences are the following. The central feature is this sense of the interconnectedness of all people and things, it's a sense of unity. And that's accompanied by a sense of sacredness or reverence for that experience. There's something humbling about that experience. And also very important, the experience has authenticity to it, a truth value to it that people will often say it's more real and more true than every day waking consciousness. In addition, there's a sense of positive moods, sometimes hard opening or love, transcendence of time and space, the past and the future collapse into the present moment, and the experiences are said to be ineffable.”
